What are the requirements for an experiment to be able to show that changes in one variable cause changes in another?(

1. The experiment must be able to establish a cause-and-effect relationship between the variables in question.

2. The variables should be clearly defined and measurable.

3. The experiment should have controlled conditions to ensure that any changes in the dependent variable are solely due to changes in the independent variable.

4. The experiment should have a control group to compare the results and rule out alternative explanations for the observed changes.

5. The experiment should be replicable by other researchers to ensure the validity and reliability of the results.

6. The experiment should have a large enough sample size to ensure that the results are statistically significant.

7. The experiment should be conducted in a systematic and objective manner to minimize bias and confounding factors.
